I just arrived at the point where I can attach my c6 to my 351w and install them as a unit. This should be easy because I have nothing but the cab on the frame of my 1948 f1.
There is still a little work to be done on the 351w. Primarily the pulleys need to changed from a "V" belt to a serpentine system.
I recall seeing a car with a serpentine system that used two serpentine belts (one belt drove only the a/c compressor) I do not know it was a 302 or a 351w but it would be just what I need since am not using a/c.

Does anyone know the answers to the two questions:
1. are the 302 and 351w pulleys interchangeable?
2. what vehicles could I find in a junk yard that would have a two belt serpentine system?

 

The two belt system was used on the late 80's 5.0 Crown Vic, Lincoln Towncar, Merc Marquis up til the end of the 5.0 in these cars (1991) Who knows, maybe you'll luck out and find a 351W cop car to get everything needed, I assume these used the same system adapted to the 351W. Pulley spacing is the same for both, it was the extra 1.3 inch of deck height in the block that spaced the heads (and their accessory bolt holes) farther up and out vs the 302/5.0
